A major premise of this book is that the physical environments in which we learn should reflect our most powerful aspirations and our most promising ideas about learning. The designs that are showcased here are about expanding rather than containing learning, opening access rather than controlling access, adapting to differences in learning modalities and preferences, rather than restricting modalities and controlling preferences. Learning by Design uses the school building as a metaphor for everything we know and think about learning and education. The authors argue that a shift to deliberate design requires a shift in mindset, from predictability and stability to informed choice and adaptation, from established patterns and procedures to flexibility and responsiveness, from established truths to inquiry and questions. This is book is for everyone who cares about education. It describes how the thoughtful design of learning environments can become the catalyst to redesign education itself in a way that allows it to fulfill its ultimate promise as the vehicle to build a more fair and just society for all.
